Subject: [PATCH 1301/1350] dts: 2712: Reduce default cma usage on Pi5
|
||
|
|
|
||
|
|
Significant cma shouldn't really be needed on Pi5 as the hardware
|
||
|
|
blocks support iommu and can access system memory.
|
||
|
|
|
||
|
|
We've migrated codec and camera support to system memory, and 3d
|
||
|
|
has always (even on Pi4) used system memory.
|
||
|
|
|
||
|
|
A large cma block causes issues with enabling NUMA on a low
|
||
|
|
memory (2G) Pi5, as cma cannot span numa regions.
